    My brand-new AT&T iPhone 18 Pro Max is still on installments, and my UnlockBase order went past the estimated time. CEO Sam Graham personally reached out, initiated a full refund, and continued helping me, even over the weekend! On Monday afternoon, November 9, 2026, my iPhone was FINALLY UNLOCKED! ? Sam truly kept his word. Amazing dedication and customer service. Thank you so much, Sam! Highly recommended!
